Spray non-contact cutting type antenna and its fabrication method

[0023]Referring to FIG. 1 and FIGS. 2˜5, a spray non-contact cutting type antenna fabrication method in accordance with the present invention includes the following four steps:

[0024]1. form a plastic shell 1, as shown in FIG. 2;

[0025]2. spray-paint the plastic shell 1 with a metallic spray paint, thereby forming a metal coating layer 2 on the surface of the assigned part of the plastic shell 1, as shown in FIG. 3;

[0026]3. cut the metal coating layer 2 into an antenna 3 subject to a predetermined pattern by means of, for example, a laser engraving technique, as shown in FIG. 4; and

[0027]4. cover the plastic shell 1 with a cover layer 4 by means of using an insert molding or spray painting technique to have the antenna 3 be enveloped in the cover layer 4, as shown in FIG. 5).

[0028]Referring to FIGS. 6 and 7, the plastic shell 1 has a feed-in contact hole 11 and a grounding contact hole 12. When spray-painting the plastic shell 1 with a metallic spray paint to form a metal coating layer f
